Application July 9, 1946, Serial No. 682,274

2 Claims. (01. 88--53) This invention relates to a hinge for a spectacle frame.

Broadly, it is an object of my invention to provide a simple hinge particularly adapted for plastic frames.

More particularly, it is an object of my invention to provide a hinge which can retain a split eyepiece to hold a lens in position within the eyepiece and also retain the temple piece.

A further object is to provide a hinge to connect the eyepiece and temple piece so that the temple piece can be folded inwardly parallel to the eyepiece and also to cause the temple piece to stop when at approximately a right angle to the eyepiece,

My hinge will avoid the necessity of applying heat to the plastic frame to expand it for receiving the lens. This method often causes distortion of the frame and mars the finish. By the use of a split eyepiece the lens can be more readily adjusted by loosening a screw and tightening it again after the adjustment. This operation will not cause any wear in the plastic material since the screw is threaded only into the metal hinge. Rivets are objectionable since adjustment is not easy and frames are caused to split.

I have overcome all of these objections by my improved hinge.

For a fuller understandin of the nature and objects of my invention reference is had to the following detailed description in connection with the accompanying drawings, in which:

Figure 1 is a top view of a hinge in open position.

Figure 2 is a top view of the hinge shown in Figure 1 in closed position.

Figure 3 is a section taken through line 3-3 of Figure 1. v

Figure 4 is a section taken through line 4--4 of Figure 1.

Figure 5 is a modified hinge.

Referring to the drawings, my hinge is comprised of two parts; numeral l represents the frame hinge portion and numeral II the temple hinge portion. The frame hinge portion ID has a square or other form of rectangular opening l2 at one end to receive the two opposed projections l3 and I4 at the end of the eyepiece. The top and bottom parts of the frame hinge portion l0 and projections I 3 and M are provided with aligned holes, the bottom hole of the hinge portion being threaded to receive the threaded end of the screw l which looks the eyepiece projections I3 and I 4 together, as shown in Figure 3. Of course, the head of screw [5 may be countersunk so that it is flush with the top of the hinge portion.

The opposite part of the frame hinge portion I 0 has a central tongue l6 projecting within a semi-circular end to receive the opposed tongues l1 and I8 of the temple hinge portion ll. Aligned openings are provided in tongues l6, l1 and 18 to receive screw l9 providing a hinge. The opening in tongue I! is threaded to receive the screw 19 the head of which may be countersunk, if desired.

A stop 20 is provided at the end of hinge portion In which prevents the temple hinge portion H from pivoting more than from the frame hinge portion l0.

Temple hinge portion I I has an indent or notch 2| which permits it to be swung parallel to the eyepiece as shown in Figure 2. Hinge portion II also has a square or other rectangular opening 22 at its opposite end adapted to receive the end of a temple piece 23. Aligned openings are provided adjacent the said end of portion I l at the top and bottom and an opening aligned therewith is provided in the end of the temple piece 23 to permit screw 24 to pass therethrough, the bottom opening being threaded to receive the threaded end of screw 24, the head of which may be countersunk. if desired.

In Figure 5 I have shown a double and triple hinge instead of the single and double hinge hereinbefore described.

It is obvious that various changes and modifications may be made in the details of construction, such as substituting another type of opening for the square or other rectangular openings l2 and 22, without departing from the general spirit of the invention.

I claim:

1. A spectacle frame hinge for a split plastic eyeglass frame having projections at the split portion comprising an extending frame hinge portion arcuately shaped at its end and a straight extending temple hinge portion, square openings at the ends of said hinge portions for receiving said eyeglass projections and the end of a temple piece within said openings, means for locking said eyepiece and temple piece within said openings "a stop at the end of said frame hinge portion to prevent said temple hinge portion fromopening more than 90", a notch at the inside of said temple hinge portion to permit said temple hinge portion to swing parallel and close to said frame hinge portion.

2. In combination with a split plastic eyeglass adapted to receive said projections and the end 6 of a. temple piece completely encasing same, screw means for releasably securing said projections and said temple piece, a stop on one of said hinge portions to prevent said hinge from opening more than 90, a cut out on the other of I 10 Number 4 said hinge portions to permit said hinge to close parallel and close to said first hinge pflrtion,

LITMAN APPLEBAUM.
